Anatomical Positions

Anatomical Positions

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Summary

This summary is machine-generated.

Right mastectomy in women with breast cancer causes more postural changes, particularly when sitting dynamically. Postoperative exercises targeting para-thoracic muscles can help maintain trunk balance.

Background:

Unilateral mastectomy can lead to postural changes influenced by dominant hand, time post-surgery, and activity.
Understanding these changes is crucial for effective rehabilitation.

Purpose of the Study:

To compare postural changes and muscle activity in static and dynamic sitting positions.
To differentiate effects between right and left unilateral mastectomy in breast cancer patients.

Main Methods:

Observational study involving 17 women post-mastectomy and 8 healthy controls.
Measured postural inclination angles using a balance board system (BBS).
Assessed muscle activity of 8 muscles in dynamic sitting positions.

Main Results:

Right mastectomy group showed increased anterior inclination when leaning forward compared to the left mastectomy group.
Right mastectomy group exhibited increased leftward inclination during anterior-left tilting.
Lower thoracic erector spinae activity was observed in the right mastectomy group when tilting backward.

Conclusions:

Right unilateral mastectomy results in greater postural alterations during dynamic sitting compared to left mastectomy in right-handed women.
Postoperative exercise programs focusing on para-thoracic muscles are recommended to improve trunk balance and mitigate postural changes.
